IMPROVEMENT IN SEED-PLANTERS.

Specification forming part of Letters Patent No. 15,182., dated June 24,1856.

To all whom't't may concern:

Be it known that I, GEORGE HALL, of Morgantown, in the county ofMonongalia and State of Virginia; have invented certain new and usefulImprovements in Operating the Seed-Slides of Seed-Planters; and Idohereby declare thatthe following is a full, clear, and exact descriptionthereof, reference being bad to the accompanying drawings, making a partthereof, in which Figure 1 represents a perspective view of theseed-planter. Fig. 2 represents a perspective view of the driving-wheelto which the operating-cams are fastened. Fig. 3 represents at'ront'view of said driving-wheel. Fig. 4 represents a detached perspectiveview, showing one of the cams when in operation.

I aware that the sliding rods of seed-planters have been operated uponby pins projecting from the sides of the driving-wheel, these pins beingof different lengths, and that the position of the driving-wheel mightbe adjusted in such a manner that the longer pins only operated upon thesliding rods, but could not be adjusted so as to have only the smallerpins operating upon the slide-rods, thus affording only an incompletemanner of adjusting the distances forhill-planting. Iwouldstatc thatthese arrangements materially difl'er from those hereinafter described.

The nature of my invention consists in so hinging the cams in thedriving-wheel that any single one can be thrown out of gear withoutchanging the position of the driving-wheel, thus afl'ording any desiredspace for regulating the distances in planting.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A represents the frame of the seed-planter, bearing on each side ahopper, B, for receiving the seeds, whence they fall into the furrowsmade by the plows 0. At the bottom of the hoppers are slide-valves forregulating the flow of the grain, as in common seed-planters, which areoperated by the connecting-rods I) in the following manner: The twoconnectingrods D are attached to the cross'head E, and

slides move with the same. Thespiral springs Gr, which are attached atone end to the frame of the machine and at the other to the crosshead E,draw the latter constantly backward,

and thus when it is freed from the action of the cams it is pulledbackward, and in this manner a vibrating motion is imparted to theslides.

'lhe peculiar construction of the catns F can be seen in Fig. 2. 'Eachcam is hinged in a recess on the hotly of the driving-wheel H in such amanner that it canbe turned on a pin, d, and that the part b can pushedinto the recess 0, so as not to project from the sides of thedriving-wheel H. When the machine is in operation the round side of thecam works against the cross-piece E, and they then assume the positionas represented in Fig. 2. When it is desired to throw one or the othercam out of gear it is only necessary to push the same into itscorresponding recess, thus enabling the operator to increase or decreasethe distances in planting by using a smaller or greater number of c ams.In a similar manner all the cams can be pushed into their recesses whenit is desired to move the machine from one location to another withoutoperating the slides and the other working parts.

Having thus fully described the nature of my invention, what I claimtherein as new, and desire to secure by Letters Patent, is

Hinging the cams that operate the seedslides to the face of thedrive-wheel, so that they can be swunginto or within recesses cut in theface of said wheel, for the purpose of adapting the machine to plantingat variable distances apart, as set forth.
